摘要： ZDMP是一个具有公共存贮器的共享总线型的多处理机系统。ZDOS是它的多机操作系统。 本文首先讨论了事件计数器及定序器与P、V操作的等价性。然后指出了事件计数器及定序器与通信原语、接口模块、路径表达式等同步机构的等价性及其实现。

Abstract: ZDOS is a multiprocessor operating system running on a shared bus multiprocessor system/The paper concludes that the event counter and sequencer are not only equivalent to PV operations, but also to other synchronous mechanisms such as communication primitives, interface modules and path expressions. Finally the implementation of these synchronous mechanizms is discussed.
